This Thunderbolt™ 3 dock gives you the connections and speed you need to boost productivity, turning your Thunderbolt 3 equipped MacBook Pro or Windows® laptop into a dual-4K workstation with up to 40Gbps of throughput. The universal laptop docking station features three USB 3.0 ports to connect your peripherals, and 85W Power Delivery to power and charge your laptop and connected devices.

Create a Dual-4K Workstation

Great for video editing and other Ultra HD tasks, this dual-4K monitor docking station supports 40Gbps speeds and 4K resolution on two monitors. Run resource-demanding applications on two independent displays, without draining system resources.

You can also connect your laptop to a single 5K monitor (using the Thunderbolt 3 USB-C port).

Connect your Devices

With three USB 3.0 ports, the Thunderbolt 3 docking station gives you plenty of ports for the latest and legacy devices. Connect USB devices like flash drives using the two Type-A ports. Keep your mobile device charged with the dock’s Fast-Charge and sync port. Connect a USB-C device with the USB-C port (5Gbps - data only).

Plenty of Charging Power

The Thunderbolt 3docking station features a 170W power adapter supporting Power Delivery to power and charge (up to 85W) your laptop, while powering all of your devices connected to the dock. This eliminates the need to use two separate power adapters for your laptop and dock.

TB3DK2DPPDUE features a rugged aluminum casing and is backed by a StarTech.com 3-year warranty and free lifetime technical support.

Applications

Review/edit images or media files on two 4K displays

Transfer a 4K movie in under 30 seconds

Transfer 3 hours of 4K GoPro® video in less than a minute

Dock and undock quickly, with a single cable for data, power, and external displays

A 4K-capable display is required to achieve 4K x 2K resolution (4K is also known as 4K x 2K).

Certain monitors may be limited to 4K at 30Hz when connecting through DisplayPort. These monitors include the following models: Dell P2715Q, Viewsonic VX2475Smhl-4K, Philips 288P6LJEB, LG 31MU97C-B, Asus PB287Q (these models will need to be set to 4K at 30Hz).

When connecting a display to one of the Thunderbolt 3 USB-C ports, a USB-C video adapter might be required depending on the input of your display.

USB 3.0 is also known as USB 3.1 Gen 1; this connectivity standard offers speeds up to 5Gbps. USB 3.1 Gen 2 offers speeds up to 10Gbps.

System and Cable Requirements

Thunderbolt 3 equipped computer with a Thunderbolt 3 port.

Your laptop's Thunderbolt 3 port must support USB Power Delivery 2.0 in order to power and charge your laptop.

Bi-directional power delivery up to 100W (not all Thunderbolt 3 devices support power delivery).

USB-C and Thunderbolt 3

Thunderbolt 3 uses the USB-C connector, but not all host connections, cables, and devices with a USB-C connector support Thunderbolt 3. This means that a USB-C device is compatible with a Thunderbolt 3 host connection, but a Thunderbolt 3 device is not compatible with a USB-C host connection. Therefore, it is important to know whether you have a USB-C or a Thunderbolt 3 host, cable, or device.

To determine if your component is a Thunderbolt 3 device, look for the Thunderbolt 3 symbol (shown below). USB-C devices do not include this symbol. For more information about USB-C, see the following FAQ: https://www.startech.com/faq/usb-c-port-capabilites.

Backwards compatibility

If you use an adapter, Thunderbolt 3 host connections are compatible with Thunderbolt 1 and Thunderbolt 2 devices. You can use the StarTech.com TBT3TBTADAP to make a Thunderbolt 3 host connections backwards compatible.

Although the Thunderbolt™ 3 standard is capable of data transfer speeds up to 40Gbps, not every cable can support this bandwidth. For example, cables over a certain length or made with certain materials are only capable of data transfer speeds up to 20Gbps.

To confirm the capability of your Thunderbolt 3 cable, refer to the information provided by the manufacturer. StarTech.com lists the capabilities of the Thunderbolt 3 cables on the individual product pages.

There are two different Thunderbolt 3 cable symbols: the 20Gbps symbol and the 40Gbps symbol. The 20Gbps symbol is composed of the Thunderbolt 3 symbol, and the 40Gbps symbol is composed of the Thunderbolt 3 symbol and the number three. These images are shown below.
